【正确答案】
Dear Mr. Wang,
Fang Gang, one of my former students at Liaodong University, is going to Chicago for post graduate studies on August 10, and I am giving him this note of introduction to you. After graduating, he remained with us for two years as assistant instructor. We found him brilliant am hard-working. I think perhaps you will enjoy meeting him as much as I know he would enjoy knowing you. And I also hope you may provide him with necessary help if he is in need.
With my best wishes for your health and happiness.
Yours sincerely,
Tang
